Image forming apparatus, method for controlling the same, and storage medium

Abstract

An printing apparatus includes a printer configured to print an image on a printing medium, a network interface configured to receive, from an external device, a print job to be held, a memory configured to store the print job received by the network interface, and a user interface configured to accept, from a user, an execution instruction for the print job stored by the memory. In addition, a controller controls the printer to print based on the print job in accordance with the execution instruction accepted by the user interface, and a power controller performs control so that power is supplied to a predetermined device of the printer based on a reception of the print job by the network interface.

Description

BACKGROUND OF THE INVENTION[0001]Field of the Invention[0002]The present invention relates to anticipatory return processing from a power-saving mode at the time of authentication printing.[0003]Description of the Related Art[0004]A Multi Function Peripheral (MFP) is equipment capable of executing a plurality of functions such as copying, communicating by a facsimile, and printing, and is generally used by sharing one or more MFPs with a few to a few tens of people. A user performs an operation in front of the MFP for using the copy function, whereas the user gives a print instruction remotely from a personal computer or the like via a network or the like for using the print function. Further, in the case of using the print function, if, for example, the user gives a print instruction to a different MFP that is not a target by mistake or the user forgets about giving the print instruction and does not pick up the printed material, the outputted printed material will be left on an ou...

AI Technical Summary

Benefits of technology

This solution significantly reduces user waiting times for authentication printing by allowing anticipatory return processing, enabling immediate user authentication and printing initiation upon arrival, while also minimizing power consumption and security risks by ensuring quick return to power-saving mode when necessary.

Problems solved by technology

Further, in the case of using the print function, if, for example, the user gives a print instruction to a different MFP that is not a target by mistake or the user forgets about giving the print instruction and does not pick up the printed material, the outputted printed material will be left on an output tray for a long time.

This may be a cause of losing the printed material or other troubles, which may induce a significant problem if the printed material is highly confidential.

Under such circumstances, the MFP is highly likely to be in the power-saving mode at the time when the user instructs the authentication printing, whereby the MFP often fails to perform printing processing immediately but starts return processing from the power-saving mode.

However, in the method of Japanese Patent Laid-Open No. 2010-004150 as well, an image forming apparatus shifts to an operation state, which allows printing, only after the completion of a user operation for authentication processing, and accordingly, a user still has to wait in front of the apparatus for a considerable time period.
